Gear racks

Gear rack drives main feature is their high level of efficiency. They are the best choice for high axial forces. This drive rigidity is constant over the whole length.They are also very cost effective for long strokes of more than 2 m.

With a rack and pinion system a slideway is driven by the pinion running on a a fixed gear rack. There is a basic difference between straight and helical toothed gear racks.Apart from typical dimensions, SCHNEEBERGER offers any cross sections with met-ric or module pitches. The max. one-piece length is 3000 mm. Joining with butt joints is possible for longer lengths.

The tooth rack can be milled or ground depending on the customer's requirements.A particular feature is that different materials and hardening processes can be used. Depending on the load to be applied you have a choice of soft, induction or case hardened or nitride hardened gear racks.

Skill and expertise are our strengths!

Standard gear racks

Straight and helical toothed gear racks are available in typical industrial dimensions from module 2 to module 12. Different materials, hardnesses and accuracy are availa-ble depending on the load to be applied.

Customised gear racks

You need a gear rack but standardised dimensions do not fit your system?No problem.You can have any gear racks up to module 20. The maximum one-piece length is 3000 mm.

The customer can choose from different materials and therefore configure the gear rack just as required.

Special is our standard.

Overview Fields of application

CUSTOMER-SPECIFIC BEARINGS AND GEAR RACKS

Exploring new shores. When research vessels investigate climatechange in the Antarctic, Schneeberger hasalready played its part in the expedition.

Our linear motion technology ma-kes an important contribution in the construction of large ships and their drive systems in particular. Gigan-tic crankshafts and driveshafts are turned, milled, ground and repaired on large, multipurpose extended-bed lathes – with exacting tolerances despite a 40 metre stroke. When our customers approach us about appli-cations such as this, we respond with custom bearings and gear racks. We also supply components for use in electricity generation, for example in the manufacturing of rotor heads or gears for wind turbines. This means we can make our own contribution to exploiting new sources of energy. Our custom bearings and gear racks can be used in any application

where standard bearings do not meet the machine builder’s requirements due to size or accuracy. The results are customer-specific, innovative solutions. We can create guideways with running characteristics, with excee-dingly high rigidity or with extremely high load carrying capacities. When you come to Schneeberger, you do not have to accept any compromi-ses. Our universal machine pool and highly competent engineers allow us to respond to complex customer de-mands for products both quickly and efficiently. Initially in small batches for prototype requirements, and then in larger series volumes, guaranteeing consistently high quality and a reliab-le, secure source of supply.

Installation Gearrackfittinginstructions/lubrication

Gear racks can be assembled in any lengths. When assembling the spacing between two gear racks must be pitch precise.Dowels may be needed for gear racks shorter than 1m.

• Aligning the first gear rack • Tighten the screws with a torque

wrench.• The torque depends on the friction

condition and strength class of the screws.

• For soft or induction hardened gear racks use screws with a strength class of 10.9. For case and through hardened gear racks use strength class 12.9.

• Align the next gear rack with a mounting plate.

• Screw the gear rack on.

• Using a measuring roller check the height deviation at the transition point and if necessary change the position of one gear rack.

• Check that the gear racks are parallel to each other.

• Finally, insert the pins if necessary.

Adequate lubrication using a lubricant adapted to the operating conditions is required to maintain the functionality of the rack drive. Lubrication protects from wear and corrosion and reduces friction.

Apart from the initial lubrication during as-sembly, the machine must be lubricated regularly during operation.

Normally electrically-driven lubrication cartridges are used for lubrication. Lub-rication greases NLGI 00 to NLGI 0 are applied to the drive pinion or the gear rack with a felt pinion.

A typical lubricant is Klüber Microlube GB 0.

Too little lubrication shortens the service life of the drive system. Therefore, always ensure that the machine is lubricated adequately.

Lubrication - instructions for use

5.1 5.1 Quality

Quality

All gear racks are manufactured on modern machine tools. The induction and through hardening is also done in-house.

It goes without saying that all SCHNEEBERGER production sites are ISO 9001 certi-fied.All process steps are self inspected by the machine operator. If required a measure-ment report is compiled on the quality of the gear rack.

The tooth rack profile complies with DIN 867, the tolerances for accuracy classes are based on DIN 3962, 3963 and 3967. The tooth rack is measured on a CNC measuring machine.

The special feature of the SCHNEEBERGER standard tooth rack is the tip chamfer. This reduces the risk of injury to a minimum.

Our concern is to provide the best industrial companies with the best products and services because that is the key to our customers' success.
